Ubisoft Massive Snowdrop Engine: BVM header (Binary Variant Map, data serialization)

[LolHacksRule]

The samples are from Mario + Rabbids Kingdom Battle, I think they are game-specific but take what you can get. Will someone figure out a way of converting the files to plaintext C++ files? Some files in games that are usually serialized are sometimes plaintext but not always... All I know so far is the byte after the header is the node count and its inverted when more than 255 nodes are used. http://tiny.cc/MRKB_BASE_BINARYSCRIPTS (Mario+Rabbids files)

Here's some hex info.

Code: Select all

4bytes (header): FF 42 56 4D (ÿBVM)
1-2bytes: Total node count, files with more than 255 nodes adds an extra byte.
1byte: Byte count for node name/string values (REPEATS FOR MULTIPLE NODES)
06-??: Node name/string value (REPEATS FOR MULTIPLE NODES)
DEPENDENT ON FILE: End of nodes/string values, ends at 01 after the last name/string value.
BEYOND: Hex values for booleans, floats, filenames, varmaps, uid, uid refs <empty> and ints, also node and string IDs.

Some scripts aren't serialized (like MGRAPHOBJECT, MUIGRAPH) for MRKB's base. http://tiny.cc/MRKB_BASE_NOTBINARY
Oh and here's the scripts that are never serialized for MRKB's base (EDITORDATA files that are 4b are excluded due to having no data). http://tiny.cc/MRKB_BASE_SCRIPTS

Thanks I honestly started to try my best at deserializing these before I saw this, MVARs are the ones I find the easiest currently, stupid question do I have to compile exes or just read its code to get ideas

[Sir Kane]

It's meant to be used as reference for writing your own code. It won't compile as is since that code is just the loading part.

Oh ok thanks then

[LolHacksRule]

Never made my own program yet... Guess I gotta look at other people's serializer tools source to get an idea

Currently did the usage command print
